A new global energy landscape is emerging, resetting long-held expectations for our energy future. Bringing together the latest data and policy developments, the World Energy Outlook 2013 presents up to date, projections of energy trends through to 2035, fuel by fuel, sector by sector, region by region and scenario by scenario. Oil is analysed in-depth: resources, production, demand, refining and international trade. Energy efficiency is treated in much the same way as conventional fuels: Its prospects and contribution are presented in a dedicated chapter. The report examines the outlook for Brazil's energy sector and provides updates on three key areas of critical importance to energy and climate trends: (i) achieving universal energy access; (ii) developments in subsidies to fossil fuels and renewables; and (iii) the impact of energy use on climate change. Oil supply, demand and trade: a fresh look at the economics and decline rates of different types of oil production around the world, the prospects for light tight oil inside and outside North America, along with new analysis of oil products and the refining sector.
